Having thought long and hard and after lots of googling, I decided that I would try my 'failing' Seagate 1TB USB disc in the USB3 interface. It works and pops up the notification message. So it appears that something has changed to affect USB3 devices such that they will only work on USB3 interface. It probably *isn't* that, but it seems that way here! -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|
